BACKGROUND OF THE INVENTION

1. Field of the Invention

The invention relates to ventilation of roofs and more particularly to a roof having improved ventilating arrangements.

2. Description of Related Art

A conventional ventilating roof is shown in FIG. 1 and comprises the following components. A pair of spaced base members 13 is formed upwardly from top edges of a roof structure 10. A ventilating ridge roll 11 having a triangular longitudinal section is spaced above the base members 13 and in covering relation thereto. A pair of side panels 12 is provided outwardly of the ventilating ridge roll 11 and spaced from the ventilating ridge roll 11, the base members 13, and the sloping portion of the roof structure 10. Thus, ventilation of a house having the roof structure 10 can be carried out by exiting hot air out of the house via a path from a gap between the ventilating ridge roll 11 and a top end of the base member 13, a space defined by the roof structure 10, the base member 13, the ventilating ridge roll 11, and the side panel 12, and a gap between a top end A1 of the side panel 12 and an outer end B1 of the ventilating ridge roll 11.

U.S. Pat. No. 8,322,088 discloses a ventilated roof structure which has the same inventor as the present invention. The U.S. Patent is characterized by that a modular roofing panel unit adapted to form part of an outermost layer of a roof which extends outwardly and downwardly to cover a space thereunder and terminates at an overhanging eave; a wall unit secured to the modular roofing panel unit distal the overhanging eave, extending downwardly to terminate at an anchored end, and disposed to partition the space under the roof into outside and inside spaces, the wall unit being configured to have a vent for communicating with the inside and outside spaces; and a modular drainage-route forming panel unit having an upper end secured to the overhanging eave with an adaptor such that a gap is formed between the drainage route forming panel unit and the overhanging eave, the modular drainage-route forming panel unit extending downwards to separate the outside space into an airflow transit chamber and an outdoor space, and terminating at an anchoring edge which is secured directly to the anchored end, the modular drainage-route forming panel unit being configured to have a drainage port which is disposed proximate to the anchored end, and which extends to communicate the airflow transit chamber with the outdoor space. A roof made based on the Patent enjoys a great success in the market. But advancement of the art is always desired.

Notwithstanding the prior art, the invention is neither taught nor rendered obvious thereby.

A roof structure 20 is provided. A pair of spaced base members 22 is formed upwardly from top edges of the roof structure 20 respectively. Each base member 22 has a plurality of first vent holes 221 on a top edge. A ventilating ridge roll 21 having a triangular longitudinal section is disposed on the base members 22 and the roof structure 20. The ventilating ridge roll 21 comprises a plurality of second vent holes 211 facing both the base member 22 and the roof structure 20, and a plurality of third vent holes 212 along a lower edge.

Ventilation of a building having the ventilating roof of the invention can be carried out by exiting hot air out of the building via an escape path from the first vent holes 221 to the second and third vent holes 211, 212. The invention can facilitate efficient ventilation of the building without consuming any power (i.e., natural convention). Further, the hotter of the weather the more efficient of the ventilation will be.

Rain water may fall into a space defined by the ventilating ridge roll 21, the base member 22, and the roof structure 20. Next, the rain water may flow downward onto the exposed portions of the roof structure 20 via the third vent holes 212 to drain. Thus, the invention is also capable of preventing rain water from entering the building.

Referring to FIG. 3, a ventilating roof in accordance with a second preferred embodiment of the invention is shown. The characteristics of the second preferred embodiment are substantially the same as that of the first preferred embodiment except the following:

A roof structure 30 is provided. A pair of spaced base members 32 is formed upwardly from top edges of the roof structure 30 respectively. Each base member 32 has a plurality of first vent holes 321 on a top edge.
